Too cool!!My tank has been running for 5 months.
My parameters have been steady but, I have noticed since April 16th my ALK has been gradually falling down from 9.3 to 8.3. I know I'm still within
limits but, I thought I should try and raise them up to ~9.0.
Using BRS' calculator I needed to add about 2 oz. of soda ash, I have never done this before.
Yesterday I gradually poured in 1oz. into my sump. When I did, my mushroom and Duncan closed up. I didn't think this was a good sign.
So last night I was searching of a way to drip it into my sump.
I came across this DIY in "Reefkeeping magazine,
Made one myself, set up dripping my ALK at 1 drop every 2 seconds.
It worked good. I don't know if the drip was too fast or not. If your interested go to above link and it explains how to make it.
